Sisämuuraus

Sisämuuraus refers to the construction of interior walls using masonry techniques. This typically involves laying bricks, concrete blocks, or other masonry units with mortar to form partition walls within a building. Unlike exterior walls, interior masonry walls are not primarily load-bearing in the same way, although they can provide structural support for floors or roofs.

The primary functions of sisämuuraus include dividing interior spaces, creating rooms, and providing fire separation between different areas of a building. Masonry walls offer good sound insulation, contributing to a quieter interior environment. They can also add thermal mass to a room, helping to regulate temperature fluctuations.

The materials used for sisämuuraus vary. Common options include lightweight concrete blocks, aerated concrete blocks (harkkotiili), and, less commonly today for interior partitions, traditional clay bricks. The mortar used binds the units together and fills any gaps. The finishing of sisämuuraus walls can range from leaving the masonry exposed for a rustic aesthetic to plastering and painting for a smooth, uniform surface.

Advantages of sisämuuraus include its durability, fire resistance, and soundproofing qualities. It can also contribute to a healthy indoor environment due to the natural materials often used. However, it can be a slower construction method compared to timber framing, and the walls are permanent, making future layout changes more challenging. The weight of masonry walls also needs to be considered in the building's overall structural design.
